The exhibit shows the AAA profile for a WLAN on an Aruba solution. This WLAN uses 802.1X to authenticate users to a RADIUS server. A user successfully authenticates with 802.1X, but the RADIUS server does not send a role assignment.
How does the Aruba firewall handle the role assignment for this user?

• A.It assigns the logon role.
• B.It does not assign a role.
• C.It applies the Aruba VSA role employee.
• D.It assigns the authenticated role.

Exhibit 2

Network administrators use the Aruba Mobility Master (MM) wizard to create a WLAN and do not manually alter any of the profiles for that WLAN. The exhibits show some of the settings for the WLAN. Some wireless users cannot successfully connect to the WLAN. Network administrators attempt to connect on their own machines with a test account, and the connection is successful. They attempt to connect with the same account on user clients, and the connection fails.
Which issue could prevent authentication from completing correctly?

• A.The user clients do not trust the RADIUS server certificate and are configured not to prompt users to trust new certificates.
• B.The RADIUS server has reached the maximum number of RADIUS clients that it can support, so it rejects new wireless clients.
• C.Some access points (APs) are not configured as clients on the RADIUS server, so user clients connected to them cannot authenticate.
• D.The user clients have unauthorized MAC addresses, so the RADIUS server rejects the authentication even though the username and password are correct.
